For UDP/TCP access, monitor uses the Monitor Password setting in the target system's security configuration. If no password is set, it uses the System Password setting in the same security configuration.
Procedure
Using IP Office Manager, access the IP Office system's security settings.
Click System and select the Unsecure Interfaces tab.
Next to the Monitor Password, click Change.
The Use Service User Credentials option can be used to disable the Monitor Password. When selected, UDP and TCP access uses the password of any service user configured for monitor access. See Configuring a service user for monitor access
Enter the existing password, then enter the new password and click OK. The default password for a system is blank.
